Comprehensive transcriptomic analysis revealing that 2-azahypoxanthine treatment induces the stress response in Arabidopsis thaliana
No full textText学術雑誌論文 / Journal ArticleSome fungi form fairy rings by secreting fairy chemicals that regulate plant growth. Among them, 2-azahypoxanthine (AHX) has been proposed as a new phytohormone, but its mechanisms remain unclear. We treated Arabidopsis thaliana with 400 μM AHX and observed growth inhibition, contrasting with earlier reports in bentgrass. To elucidate this effect, we performed transcriptome sequencing and identified differentially expressed genes. Gene ontology enrichment revealed activation of hormone- and stress-related terms and suppression of photosynthesis-related terms. Liquid chromatography-mass spectrometry further showed an increase in 1-aminocyclopropanecarboxylic acid, an ethylene precursor, after AHX treatment. These results suggest that AHX alters the stress response in A. thaliana by regulating genes associated with multiple plant hormones, including abscisic acid, ethylene, jasmonic acid, salicylic acid, and cytokinins.This is a pre-copyedited, author-produced version of an article accepted for publication in "Bioscience, Biotechnology, and Biochemistry" following peer review.

A Study on Essential Elements for Problem-Solving Learning in Life and Social Studies: Through a Three-year Study of the Practice of Tomoyo Watanabe
Get PDFText紀要論文 / Departmental Bulletin Paper3年間にわたる小3社会科および小1生活科の渡辺知世実践全体を考察し，生活科および社会科の問題解決学習に不可欠な要素として次の5点を導き出した。①子どもたちが対象に働きかけるようになること。②子どもたちが働きかける対象とは，子どもの外側にある事物と，同時に，ともに学習をしている友達の両方であること。③子どもの外側にある事物は，子どもの意志ではどうにもならないもの，例えば自然の摂理のような矛盾を含むものを設定すること。ただし，その際には，子どもが①②を活発に出来て，その楽しさを体得するようになるタイミングを見計らう必要がある。④①から③を通して，子どもの認識が自分に向かうようになること。⑤真の仲間。departmental bulletin pape
